Journal ArticleDOI
Success and failure in human spermatogenesis as revealed by teratozoospermic RNAs
Adrian E. Platts,David J. Dix,Héctor E. Chemes,Kary E. Thompson,Robert Goodrich,John C Rockett,Vanesa Y. Rawe,Silvina Quintana,Michael P. Diamond,Lillian F. Strader,Stephen A. Krawetz +10 more
TL;DR: A cross-platform microarray strategy was used to assess the profile of human spermatozoal transcripts from fertile males who had fathered at least one child compared to teratozoospermic individuals and revealed the transcriptional perturbation common to the affected individuals.
Journal ArticleDOI
Overexpression of the insulin‐like growth factor 1 receptor (IGF‐1R) is associated with malignancy in familial pheochromocytomas and paragangliomas
María Celia Fernández,Ayelen Martin,Marcela Venara,María de Luján Calcagno,Gabriela Sanso,Silvina Quintana,Héctor E. Chemes,Marta Barontini,Patricia Pennisi +8 more
TL;DR: Pheochromocytomas and paragangliomas (pheo/pgl) are neuroendocrine tumours derived from chromaffin cells and increased IGF‐1R expression has been shown during progression to metastatic phenotypes of several types of cancer.
Journal ArticleDOI
Expression of dysadherin in the human male reproductive tract and in spermatozoa
Nieves María Gabrielli,Maria Florencia Veiga,María Laura Matos,Silvina Quintana,Héctor E. Chemes,Gustavo Blanco,Mónica H. Vazquez-Levin +6 more
TL;DR: This is the first report on expression of dysadherin in the male gonad and in spermatozoa and leads us to postulate a role for dys adherin as a modulator of sperm function.
Journal ArticleDOI
Origin and evolution of somatic cell testicular tumours in transgenic mice.
Silvina Quintana,Marcela Venara,Rodolfo Rey,Rodolfo Rey,Nathalie di Clemente,Héctor E. Chemes +5 more
TL;DR: The histological and immunohistochemical phenotype of tumours suggests a mixed differentiation of somatic cells of the specialized gonadal stroma, compatible with a common origin of Leydig and Sertoli cells from the specific stroma of the gonadal ridge.
